Female genital tracts of six to eight years Baladi cows (n=30) were collected
from Belevia abattoir of Beni-Suef province during the period from March
2016 to May 2016 to investigate ovarian abnormalities and uterine changes
in cattle based on histopathology. Prevalence rates of granulosa cell tumors
were 26.67% and 38.89% in right and left ovaries, respectively. Follicular
cysts could be detected in both ovaries with percentages of 50.0% and
44.44%, respectively. The most predominant pathological lesions in ovarian
medulla were hyalinosis of blood vessels and mononuclear cell infiltration.
The main uterine pathological alterations were endometritis associated with
degenerative changes and necrosis in the endometrial linings in most cases
(n=25), endometriosis (n=13). Variable degrees of congestion from
moderate (n=25) to highly congested (n=5) were elucidated. Perivascular
cuffing (n=2) and perivascular fibrosis (n=3) of uterine blood vessels could be
detected. Immunohistochemically, granulosa cell tumors were positive to
vimentin and negative to inhibin.
